Here's something you could try:
Allow Apps Installation from Unknown Sources
For the security reasons, the Android smartphone does not allow you to install apps from third-party sources or sources apart from the Google Play Store. Installing third-party apps from unknown sources can harm your Android phone.
So, if you are trying to install a .apk file then you may face the “parse error – there is an error parsing the package”. To fix this, what you can do here is allow app installation from the unknown sources. You can find the settings to the same under Security settings of your phone.
To allow app installation from the unknown sources, go to Settings and look for Security option under “Input and Control.”
Tap on Security and under Device administrators tap on “Unknown Sources, allows installation of apps from unknown sources”. If asked to confirm, tap OK.
Go back to the folder where you have the .apk located. Tap on it and install the app without parse error.

Your device does not have enough RAM and a high enough
version of Android to play the game.
You would need to root your device and try out this hack:

A PC must be used for installation, if the APK
Editor fails... at least that's what people have tried/tell me.. I'll try to
make a new video soon for that (so please like and subscribe to show support).

Unfortunately that model does not have enough RAM to run the game and as far as I'm aware this rooting hack is the only safe option... I will be posting new hacks (without rooting) if I can find them so like and subscribe to get my latest videos!

Download the appropriate system image for your device below, then unzip it to a safe directory.
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
Using the adb tool: With the device powered on, execute:
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
If necessary, unlock the devices bootloader using one of the following methods:

If you are updating a Nexus or Pixel device that is manufactured in 2015 or later (for example, a Nexus 5X, Nexus 6P, Pixel, Pixel XL, Pixel 2 or Pixel 2 XL device), run this command:
For Pixel 2: To flash the bootloader, Pixel 2s boot loader must be updated to at least Oreo MR1s version first. This may be done by applying an over-the-air (OTA) update, or sideloading a full OTA with the instructions on that page.
For Pixel 2 XL only with loader version prior to TMZ20a: the critical partitions may also need to be unlocked before flashing. The unlock can be performed with this command, and should NOT be done on other devices:
If you are updating an older device, run this command:
The target device will show you a confirmation screen. (This erases all data on the target device.)
See Unlocking the bootloader for more detailed instructions.
Open a terminal and navigate to the unzipped system image directory.
